Appeal Number: 2006-1385
Application Number: 10/452,753
We turn next to claim 7. Appellants assert (Br. 9) that Shridhara and Beesley
do not teach maintaining satellite positioning system receiver signal gain during
blanking. We agree. From our review of Shridhara and Beesley, we find no
suggestion for maintaining satellite positioning system receiver signal gain during
blanking. We conclude that the prior art fails to establish a prima facie case of
obviousness of claim 7. Accordingly, we cannot sustain the rejection of claim 7
under U.S.C. § 103(a) as being unpatentable over Shridhara in view of Beesley.
We turn next to claim 8. Appellants provide no specific arguments regarding
this claim, but generally argue that Shridhara and Beesley do not disclose the
claimed features. From our review of the record, we find that Shridhara discloses
storing a satellite positioning system correlator output signal and detecting the
presence of a jamming signal in the satellite positioning system receiver by
analyzing the stored information (col. 4, ll. 39-43). Therefore, we are in agreement
with the Examiner that the teachings of Shridhara would have suggested to an
artisan the invention set forth in claim 8.
For the lack of any specific arguments by Appellants, and our agreement with
the Examiner’s position, we are not persuaded of any error in the part of the
Examiner regarding the rejection of claim 8. Accordingly, the rejection of claim 8
under U.S.C. § 103(a) as being unpatentable over Shridhara in view of Beesley is
sustained.
We turn next to claim 9, which depends from claim 8. Appellants assert (Br.
10) that none of the references analyze a stored correlator output signal to identify
a characteristic of a jamming signal and synchronize the blanking signal with the
jamming signal based on the identified characteristic. We agree. From our review
of Shridhara and Beesley, we find no suggestion for identifying a characteristic of
